The power of the internet and YouTube is a lot more manufactured than you may think. See the recent ACBDEFU origin drama (artist posts about trying to come up with a song, Marketing Manager from her record label just so happens to comment the idea on her video, song sees strong commercial success just a week later).
It's totally possible an artist makes a break on the internet. Sarah Crean blew up from 200 monthly listeners to almost 200,000 overnight because a music TikToker posted about how great her songs are as an independent artist. (TBH it is, go check it out)
Being independent is totally a way you can go, but if you'd want to make money in the industry to really live off of you have 2 options:
- Work a job (or 2) for hours a day to keep yourself fed/housed while also doing the job of 5-10 people to try to get your music noticed enough to make money directly from fans.
- Sign up with a label, immediately get your daily life taken care of and focus on your music full time.
Sadly, for a lot of artists, the promise of being able to quit your job and focus on your passion full time is an offer too lucrative to turn down. It's an exploitative industry, but when it works it works. And when it fails, it's the artist that's left on the side of the highway. Labels are like casinos, the house never loses.
